A recent study published in Medicina Clínica has observed the effect that a Mediterranean diet supplemented with extra virgin olive oil or nuts has on the fatty liver index (FLI). A total of 276 participants with an average age of 67 years old and free from cardiovascular disease at baseline took part in the study. Three intervention groups were created (MedDiet+Extra Virgin Olive Oil; MedDiet+Nuts and the control group). The time trend of the change in the FLI and participants’ BMI was significantly lower in the MedDiet+Nuts group when compared with the control group. The study concluded that a dietary intervention following a Mediterranean diet could delay the natural progression of non-alcoholic fatty liver disease.Cueto-Galán, R., Barón, F.
